Water inside the fire protection pipelines stand still unless a fire or seismic movement condition occurs. Because of no thermal movement expected, fire protection pipelines are often completed with no flexible part.

This rigid structure must be protected against unexpected movements just like the building settlements and seismic motions, most important areas to be protected during such an event are the dilatation points. Modern buildings are consisted of multiple independent sections the areas between two building is called dilatation point.

The pipelines pass through from one building to another should be protected with seismic motion absorption joints. Ayvaz produces FM approved expansion joints and loop joints for fire protection pipelines.
